Contingent Allegiance Condition - IBM DCAS-32160 - Ultrastar 2.1 GB Hard Drive Specifications

11.16 Contingent allegiance Condition

The contingent allegiance condition shall exist following the return of Check Condition, except Check Con-
dition caused by Invalid LUN. Execution of all queued commands shall be suspended until the contingent
allegiance condition is cleared.
The contingent allegiance condition can be cleared by the initiator in one of the following ways:
By issuing a REQUEST SENSE command to the Target and receiving the sense data. This is most
recommended way.
By issuing any other command to the I_T_x nexus that reported the fault.
By issuing an Abort message to the I_T_x nexus that reported the fault. This will also abort the current
and queued I/O process from that initiator.
By issuing a Bus Device Reset message to the Target. This will also abort all current and queued I/O
processes.
By generating a RESET condition on the bus. This MUST be the last resort.
